Discussion

  • Males and females are assumed to have the same parameters

Facts

  • Males convert to females after one or 2 yr (secondary females); primary females comprise half of the population (Ref: Alle1959)
  • 6 larval moults, the 7th involves metam; 14 moults to grow from 21 to 93 mm; 4 moults are required to transform from male to female (Ref: Alle1959)
